turn off the power. Be sure to hold the connector when disconnecting cables. Pulling a cable with excessive force may cause the core of the cable to be exposed or break the cable, and this can lead to fire or electric shock.

(3) This product contains glass. If shock, vibration, heat or

distortion is applied to the product, the glass may be broken.

(4) If glass surface of the display breaks or is scratched, do

not touched the broken pieces or the scratched with bare hands. You may be injured.

(5) LCD Module requires to be handled with special care. LCD

Module is not to be touched with metal or hard materials. Must not be stressed by heat or mechanical impact.

(6) There are some particular components on the rear panel of

this product. Skin contact with these components may cause an electric shock. So, handle with care.

(7) While moving the product, be sure to turn off the power,

disconnect all cables and watch your step. Dropping the product may cause injuries from electric shock. So, while moving the product handle with care.

(8) When cleaning the panel is necessary, wipe it with a soft

and moistened cloth a neural detergent. Caution on connector area. Do not use chemicals such as thinner or benzene.

(9) LCD Module emits heat from the Lamp, Backlight lamp,

component parts. Therefore, the environmental

temperature must not exceed 50

Inverter system is driven by high voltage, so it must avoid

conductive materials.

(10) If repairing components with a lead line, high voltage or

high temperature components must be put out from a lead line and fix.

(11) Do not place an object on the surface of the display. The

glass may break or be scratched.

(12) This product may be damaged if it is subject to excessive

stresses (such as excessive voltage, current, or temperature). The absolute maximum ratings specify the limits of these stresses.

(13) Do not cover or wrap with any covering materials while

power is applied to the product.

(14) This product is made from various material such as glass,

metal, and plastic. When discarding it, be sure to contact a purchase place.

(15) If a discrepancy occurs due to any arbitrary modification

or disassembly, LG.Philips LCD is not responsible for function, quality or other items.

(16) Within the warranty period, general faults may be charged

for depending on responsibility for the faults. You handle with care.

SERVICING PRECAUTIONS

Color TFT LCD Module is apt to be damaged by both electrical and mechanical stresses. Users, therefore, are requested to follow the “Servicing precautions of color TFT LCD Module” on the followings.

www.panelook.com

System Assembler

(1) Follow power sequence.

Abnormal power sequence may cause critical malfunction or electrical damage.

(2) Prevent physical stress.

(3) Prevent overheat.

High temperature on the surface of the screen may cause poor quality. Please make LCD Module used on specified temperature. Low temperature under 10 makes LCD Module respond slowly, make Backlight worse operated and shorten very much the lifetime accordingly.

(4) Keep LCD Module dust-free.

LCD Module is sensitive against dust.

Dust can cause visual or functional problem.

(5) Do not touch TCP area.

Do not touch TCP area at any case. It causes Driver IC crack, film crack etc. TCP is the weakest point of LCD Module.

(6) Do not pull Backlight wire.

Please do not pull the Backlight wire it can cause the wire disconnected or damaged.

(7)Check a connection of the Inverter & Backlight

connectors.

Incomplete connection with can cause burnt in Backlight connector or damage the inverter.

(8) Handle with care.

Please do not drop, bend or hit the LCD Module. Physical stress can cause the defect such as broken.

(9) Keep mounting screw length and motor driver’s torque.

Strong weaken motor driver’s torque can make a mechanical defect on LCD Module. Please keep the specification.

(10) Do not operate for a long time under the same pattern.

Operating LCD Module for a long time under the same pattern can cause image persistence and can damage it.

(11) Defect panel also handled with care.

To prevent making another defect, please handle the defective LCD Module as a good one. Defective LCD Module should be repaired.

(12) Do not stack LCD Modules.

LCD Module consists of fragile components such as TCPs or Glasses. Stacking LCD Module can cause undesired defects.

(13) Do not provide strong pressure at connecting.

Strong pressure can transfer the force to TCP which is the weakest parts of LCD Module. Eventually can make TCP crack or other unexpected defect.

(14) Let the Backlight Wire backside of LCD Module.

If let the Backlight wire front side of LCD Module, the Backlight connector can hurt the surface of polarizer.

System Assembler/End User

(1) Keep clean the surface.

Please wear rubber glove when touch the surface of LCD Module screen. Please use soft and anti-static material with n-Hexane as cleaner.

(2) Be careful not to make polarizer scratch.

Surface of polarizer is soft, so it’s easily scratched. Please do not touch, press or rub on polarizer surface with materials over HB hardness.

(3) Be careful swift Temperature & Humidity change.

Swift temperature and or humidity change can make dew condensation or ice which cause nonconformance such as malfunction.

(15) Never connect/disconnect at power on.

LCD Module consists of CMOS which is known as weak component against EOS. It can hurt the product.

(16) Electro-static discharge can make damage.

Semi-assembled product should be handled with wrist strap. Earth human body when handle the LCD Module. Please do not touch the interface connector pin.

(4) Keep out of water.

Water on in the LCD Module can cause electrical short or corrosion. Please wipe out or dry water carefully.

(5) Keep LCD Module corrosive gases free.

Corrosive gas makes the polarizer and the circuitry parts chemical damages and eventually cause defects.

(6) Keep the suitable temp. & suitable humidity.

High temp. & high humidity shorten the lifetime.

General Description

TFT-LCD is made up of the lower plate glass with TFT, the upper plate glass with color filter, the middle Liquid Crystal. TFT convey and control the signal and the Liquid Crystal control transmitted ray as molecular structure different by admitted volt. And as the ray pass color filter, show up the wanted color and picture. The LP141WP1-TLA1 is 14.1 inches diagonally measured active display area with WXGA+ resolution(900 vertical by 1440 horizontal pixel array). Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot, thus, presenting a palette of more than 262,144 colors. The LP141WP1-TLA1 has been designed to apply the interface method that enables low power, high speed, low EMI. The LP141WP1-TLA1 is intended to support applications where thin thickness, low power are critical factors and graphic display are important. In combination with the vertical arrangement of the sub-pixels, the LP141WP1-TLA1 characteristics provide an excellent flat display for office automation products such as Notebook PC.
